PROBLEM TO BE SOLVED: To provide a method and device that analyze water purity at an outlet of a purifier.SOLUTION: A water purifier comprises filtering means 1, oxidation means 2, and water polishing means 3 arranged in series, with one resistivity measurement cell 4 arranged in series between an outlet 22 of the oxidation means 2 and an injection point 31 of the polishing means 3. The purifier also includes a control and calculation part 7 and a display device 8 for providing an operator with obtained information on purity in real time. A calculation module 10 determines a resistivity &rgr; with infinite liquid by regression and calculates the amount of an organic compound contained in purified water. |
